Quantum mechanics is arguably our most successful physical theory, yet the nature of the quantum state still constitutes an ongoing controversy. This paper proposes, articulates, and defends a metaphysical interpretation of the quantum state that is fictionalist in spirit since it regards quantum states as representing a fictional ontology. Such an ontology is therefore not physical, and yet it provides a reference for the language used in quantum mechanics and has explanatory power. In this sense, this view, akin to Allori’s recent account of wavefunctionalism, combines elements of the representationalist and anti-representationalist camps and aims to be the best of both worlds.

量子力学可以说是我们最成功的物理理论，但量子态的本质仍然存在持续的争议。本文提出、阐明并捍卫了一种对量子态的形而上学解释，这种解释在精神上是虚构的，因为它认为量子态代表了一种虚构的本体论。因此，这样的本体论不是物理的，但它为量子力学使用的语言提供了参考，具有解释力。从这个意义上说，这种观点类似于阿洛里最近对波功能主义的解释，结合了表征主义和反表征主义阵营的元素，旨在成为两个世界中最好的。
